I can't log into the game.

Guys, I can't log into the game. I downloaded the Mists of Pandarian expansion but it doesn't log into my account. In the WLK expansion, it logs in normally. Does anyone know why? I have to download something else besides the expansion. Detail: Am I downloading it through the torrent option?

Is the server really online?

I downloaded WoW WotLK and it worked, but WoWMP doesn't work, it doesn't log in. What do I need to do to make Mists of Pandaria work? Does it need some kind of update or something like that?

General "can't login" guide:

1. Restart your PC.
2. Close and exit torrent.
3. Move your WoW -folder to other folder, away from Torrent's Download folder.
4. Right click WoW -folder or config.wtf -file, select properties, un-check "Read-only" and Apply.
5. If you get prompt, Apply changes to this folder, sub-folders and files and click OK.
6. Warmane realmlist guide
7. Login by using username, not email.

If you still can't login, either it's temporary network issue, or your ISP is blocking the connection. Trying VPN might be the only option at that point.

I had already tried those options, there may really be some blockage, thank you for the help.

What's the error message you get when trying to login to MoP?
